Editor's note: Amity between the people holds the key to sound state-to-state relations.

As the Japanese saying goes: "Don't walk behind me; I may not lead. Don't walk in front of me; I may not follow. Just walk beside me and be my friend." While this embodies companionship, it only partially captures the dynamic and enduring partnership between Tianjin in northern China and Kobe in western Japan. Their relationship is a fascinating dance of sisterhood and mutual support, forged over decades of collaboration since the two became friendship cities.

China and Japan normalized their relations in September 1972, setting the stage for interactions at all levels. Just a year later, in 1973, Tianjin and Kobe embarked on a new journey of friendship. On June 24, 1973, they signed a friendship city agreement, the first of its kind between a Chinese city and a Japanese city. The pact marked the beginning of a relationship that transcends national and political boundaries, forging a special bilateral bond.
